According to police sources, squads from Ankara Provincial Gendarmerie Command conducted simultaneous raids on five different locations on Friday, targeting the "urban organization of the PKK", which is listed as a terrorist organization by Turkey, the U.S. and the EU.

Friday's raids followed a wave of similar anti-terror operations by Istanbul police on Thursday in the city's Umraniye district targeting supporters of Daesh, the PKK and the Revolutionary People's Liberation Party-Front (DHKP-C) after police defused a bomb in the Okmeydani district late on Wednesday.

Turkish security forces have detained more than 1,300 suspects nationwide since July 24, according to the prime minister's office.

The recent counter-terrorism crackdown came after the country's southeastern border regions were hit by a series of attacks which started in Sanliurfa with a July 20 suicide bombing blamed on Daesh that killed 32 people, plus the fatal shooting of two police officers -- claimed by the PKK -- two days later.
